Application filed June 17, 1914. Serial No. 845,734.

To all whom it may concern:

Be it known that I, ARTHUR M. STEVENS, a citizen of the United States, and resident of Derry, county of Rockingham, State of New Hampshire, have invented an Improvement in Devices for Feeding Liquid on the Selvage of Cloth or other Material, of which the following description, in connection with the accompanying drawing-is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in apparatus for treating cloth and particularly to devices for feeding a liquid upon the selvage of cloth or like material.

Inthe manufacture of some kinds of woolen and worsted cloths it is customary to provide the selvage with cotton warp threads. hen cloth thus made is passed through the carbonizing apparatus the action of the acid upon the cotton threads injures and in some instances destroys the same, thus causing a weakness of the selvage of the cloth. Such action of the acid is most pronounced during the time that the cloth is passing through'the drier after it has been passed through the acid bath of the carbonizer.

One of the objects of the present invention is to provide means for feeding a suitable liquid such as an alkali upon the selvage of the cloth at a predetermined distance from the edge thereof which will neutralize the acid and prevent the otherwise injurious effect of the bath through which the cloth or like material has been passed.

It is of course essential that in feeding the liquid upon the cloth a continuous application of such liquid shall be made. Another object of the invention therefore is to provide means for feeding a regulable quantity of fluid continuously in a defined path upon the cloth.

matic view of a carbonizing machine and drier showing the manner in which the present invention is applied to theweb of cloth as it passes from the carbonizer to the drier. Fig. 2 is an end elevation of one of the preferred embodiments of my invention showing the cloth feeding rolls, the fluid tank, the conduit leading therefrom to the cloth and the guidefor the nozzle of said conduit. Fig. 3 is a front elevation of the same broken away in the middle, and, Fig. 4 is a detail end elevation of the feeding roll and the means for delivering the liquid therefrom to thg conductor which leads to the delivery tu e.

Fig. 1 illustrates an assembledocarbonizing and drying apparatus in which the cloth 1, or like material is brought to the vicinity of the carbonizer upon a wheel truck 2, in the usual manner and is carried therefrom over a guide roll 3 into an acid tank 1- having a disposed near the bottom and top and which may have a pair ofsqueeze rolls 6, 6, intermediate of the length of the tank in the usual manner and pairs of delivery rolls 77 and 8-8 from which the web of cloth 1 is led to a drier which may be of the usual form having a series of alternately disposed rolls 9, 10 within a suitable casing (not shown) and from which the'cloth may be discharged over guide rollers 11, 12 and directed by suitable guide rolls 13 upon a truck 14. As illustrated in this diagrammatio sketch the apparatus for feeding liquid upon the selvage of the cloth is placed adjacent to the delivery rolls 88 and preferably between said pair of rolls and a pair of supplemental rolls 15-15 located a short distance therefrom. V

The liquid feeding and distributingmechanism which will hereinafter be more fully 1- 1e cribed comprises in general a tank 16 within which is mounted a preferablysmooth feeding roller 17 partly submerged in the liquid in said tank." A trough or scraper 18 pivotally mounted upon a cross bar rests upon the surface of the roller and serves to-scrape the liquid therefrom and to "discharge it into a funnel 19 at theupper end of a flexible tube 20 which leads to a pointed delivery nozzle or tube 21. preferably of glass the end of which is supported above'and adjacent to the selvage of the cloth and is maintained in contact therewith by a guide rod 22 which rests against the edge of the cloth and maintains the delivery nozzle 21 at a uniform distance from the edge of the cloth regardless of unevenness which may appear in the selvage. Any suitable mechanism may be utilized for supporting the apparatus thus described, a convenient form however is shown in Figs. 2 and 3 of the drawing in which the delivery rolls 8-8 are journaled in standards 23 rising from the end of the carbonizing tank 4 or an extension thereof, the upper end of said standards 23 being provided with a cross piece 25 adapted to support the tank 16 it being understood that the tank may be of suflicient length to extend across the machine or it may be in sections.

The rollers 17, for delivering the liquid from the t ank may be supported on a shaft 26 suitably journaled in the frame and provided with a sprocket wheel or pulley 27 at its end which may be driven by achain or belt 28 passing over said sprocket wheel or pulley and a supplemental sprocket wheel 29 which desirably may be supported in journals upon the end of a bracket 30 secured to the end of the tank 4 said sprocket wheel or pulley 29 being driven by a chain or belt 31 passing over a sprocket wheel or pulley 32 on a shaft of one, preferably the lower, of the pair of delivery rolls 8. Suitable means mav if desired be provided for driving the roller 17 at different speeds in order to control. the amount of liquid delivered to the distributing nozzle.

The roll 17 may be of a sufficient length to extend entirely across the machine and thereby adapted to supply liquid to the delivery device at any point throughout the width of the machine or may be made in short sections as illustrated in Fig. 3, for example, one for each end of the tank. The scraper 18 is desirably trough shaped in form and having a beveled upper edge, and

.is mounted upon a bar 33 conveniently supported by brackets 34: on theends of said tank 16 adjacent to and in front of the roll 17, the upper edge of the trough 18 resting upon the surface of the roller 17 above the axis thereof as illustrated in Figs. 2 and 4.

Itwill be observed that the rotation of the roller in a clockwise direction will deliver a small amount of fluid continuously through the trough 18 into the funnel 19 whence the same will pass through the tube 20 to the delivery nozzle 21.

The tube 20- with its funnel 19 may be supported in any desired manner beneath the discharge end of the trough 18 so that it may be adjusted laterally with said trough to provide for the application of the fluid to webs of cloth of different widths, this however is usually unnecessary as the adjustment of the guiding device is ordinarily suflicient to provide-for the application of the liquid to the selvages of webs of usual dimension.

The guide 22 may of course be supported in any desirable manner. In the embodito the edge of the cloth.

ment shown herein this guide 22 is provided. with an eye 35 at its upper end by means of which it is mounted upon. a cross bar 36 supported by suitable brackets 37 projecting laterally from the ends of the cross piece 25 and in operation the rod is normally supported in .an inclined position as shown in Fig. 8 so that its end rests against the edge of the selvage and is confined between an upper and lower tension rod 3S39 which may be supported by stands a0 rising from the brackets 30 and may extend inwardly over the selvage of the cloth a short distance as illustrated in Fig. 3 or if desired may extend entirely across the frame. These tension rods serve to keep the selvage of the cloth taut at the point at which the liquid is applied thereto by the nozzle 21 as well as to retain the guide 22 in proper relation The said guide rods 22 may be maintained in contact with the edge of the cloth by means of a lateral arm -11 which may if desired be provided with a suitable weight so adjusted as to force the end of the rod 22 against the edge of the webof cloth with any desired pres sure.

In the operation of the device the web of cloth is first passed through an acid carbonizing bath of dilute sulfuric acid or the like in the manner aforesaid, thence through the squeezing rolls 7-7 and the delivery rolls 88 to the supplemental delivery rolls 1515 and thence to the drier. The device for applying liquid to the selvage thereupon delivers a continuous amount, which may be a very fine stream, of an alkali, such as a dilute solution of soda and water, or ammonia, to the selvage of the cloth thereby neutralizing the acid and preventing further action of the acid upon the fibers of the selvage as the cloth is passed through the drier.

By the use of my improved apparatus in combination with the carbonizer and drier the fibers of the selvage of the cloth, other than wool, such as cotton, are prevented from being burned out or injured by the acid and the cloth is delivered from the drier in perfect condition so far as the selvage is concerned.

It is to be understood that the embodiment of the invention described herein is illustrative merely and is not restrictive and 2.
